A boiler that won't fire, a radiator that won't heat, or a pressure gauge that keeps climbing — boiler problems come in every shape. The good news is most boiler failures in Vancouver homes are diagnosable and fixable by a certified technician who's seen the full range of system types in the Lower Mainland.

We connect you with gas-certified boiler repair technicians across Metro Vancouver. They carry diagnostic equipment and common parts, and they know the specific failure modes of the boiler brands and distribution systems that are common in BC.

Don't let a boiler issue sit. Small problems — a weeping pressure relief valve, intermittent ignition failures, water hammer in the baseboards — have a way of becoming expensive failures if ignored. Call us and get it looked at.

What Boiler Repair Involves

System Diagnosis

Boiler repairs start with proper diagnosis, not guesswork. Our technicians use combustion analysers, pressure gauges, temperature probes, and electrical testers to identify the actual fault. Firing up a boiler with an undiagnosed problem can make things worse — we find the cause before we start replacing parts.

Control Board & Ignition Repairs

Ignition failures (no spark, flame not proved, intermittent lockout) are among the most common boiler repair calls in Vancouver. We diagnose ignitor condition, flame sensor contamination, gas valve operation, and control board function. Intermittent ignition faults are often caused by a corroded flame sensor — a 15-minute fix if caught early.

Circulator Pump Repairs & Replacement

A failed circulator pump is a classic no-heat call — the boiler fires but the heat doesn't reach the rooms. We test pump operation, check wiring, and replace failed pumps with appropriate replacements (Grundfos, Taco, or manufacturer-original units). Most residential circulator replacements take under two hours.

Pressure & Leak Repairs

A boiler losing pressure is leaking somewhere. We locate the source — could be a weeping pressure relief valve, a corroded fitting, a leaking expansion vessel diaphragm, or a baseplate crack. Finding the actual leak source often requires pressure testing isolated sections of the system.

Zone Valve & Thermostat Repairs

A zone that won't heat despite the boiler firing is often a failed zone valve or a wiring fault in the zone circuit. We test zone valve operation, verify thermostat function, check the end switch operation, and repair or replace faulty components.

Heat Exchanger Inspection

A cracked heat exchanger is the most serious boiler fault — it can allow combustion gases to enter the heating water, which in severe cases creates a CO risk. We inspect heat exchangers during every service call and recommend appropriate action if cracking is found.

Technical Details

  • Common boiler fault codes in Navien, IBC, Viessmann, and Bosch units are mapped in our technician documentation — they're the first diagnostic step on digital boilers with display panels.

  • Boiler water chemistry matters for repair outcomes. High chloride content, acidic condensate bypass, or oxygen infiltration through open-system expansion tanks accelerates heat exchanger corrosion. We check and note water chemistry on every service call.

  • Pressure relief valve replacement requires an exact pressure rating match. Installing a mismatched PRV is a code violation and a safety hazard.

  • Circulator pump selection must match the system's head pressure and flow requirements — an undersized circulator causes cold zones, an oversized one creates noise and premature valve wear.

  • Error code E003 (Navien) indicates ignition failure. Common causes: weak ignitor, contaminated flame sensor, gas valve issue, or venting restriction causing premature safety shutdown.

Frequently Asked Questions

Why is my boiler making a banging noise?+
Banging in a boiler is usually kettling — limescale or sludge build-up on the heat exchanger causing localised boiling. It can also be water hammer in the distribution pipes from fast-closing zone valves. A technician can determine the cause and recommend whether a system flush, scale inhibitor treatment, or a valve change will resolve it.
Why does my boiler keep losing pressure?+
A boiler losing pressure is leaking somewhere. Common sources: a weeping pressure relief valve (most common), a failing expansion vessel, a corroded fitting or valve, or a small crack in a baseboard or pipe. We find the source and fix it — just re-pressurising the system without finding the leak will have it dropping again within days.
Why won't my boiler fire?+
No-fire can be caused by a failed ignitor, a dirty flame sensor, a closed gas valve, a lockout due to overpressure or overtemperature, or a faulty control board. The boiler's display or indicator lights usually give a starting point. Our technicians diagnose the actual fault rather than guessing parts.
One zone of my home doesn't get heat — what's wrong?+
A single dead zone usually points to a failed zone valve, a wiring fault in that zone's circuit, an air-locked baseboard, or a stuck thermostat. We test each component in sequence to find the fault quickly.
How long does a boiler repair take?+
Most common boiler repairs — ignition fault, circulator pump, zone valve, pressure relief valve — take one to three hours. Repairs requiring parts that aren't on the truck may require a return visit once parts arrive.
